Between Lake Constance, a natural jewel flanked by the surrounding gently rolling countryside, and Basel, the cultural centre of the three-border region where Switzerland, France and Germany meet, EuroVelo 15 travels east to west, taking the south bank of the Rhine in Switzerland, and switching to the north bank in the German State of Baden-Württemberg. The route passes through Schaffhausen and its famous waterfall – the largest in Europe – and the many quaint towns and villages spanning the river in Germany and Switzerland.
